AI Technical Summary

Technical Problem

The existing blood collection tube caps are prone to misinstallation or loosening during testing, affecting testing accuracy. Furthermore, the caps need to be manually removed after testing, which is cumbersome and easily damaged.

Method used

A sealing test device for blood collection tube caps was designed, comprising a test platform, an inflation tube, a pressure sensor, and an electro-hydraulic actuator. The piston and connecting rod are controlled by the electro-hydraulic actuator to achieve automatic fixing and disassembly of the cap body, and the sealing performance is monitored in conjunction with the pressure sensor.

Benefits of technology

It enables automatic fixing and disassembly of blood collection tube caps, improves testing accuracy, reduces operational difficulty and labor intensity, and ensures the accuracy of sealing tests.

Abstract

The utility model relates to the technical field of blood collection tubes, and discloses a sealing test type blood collection tube cover device which comprises a test board and a cover body, a test groove is vertically formed in the upper surface of the test board, the size of the sealing end of the cover body is matched with that of the test groove, and an inflation tube is fixedly installed above one side of the test board. According to the utility model, the sealing end of the cover body can be inserted into the test groove, the electric-hydraulic push rod is controlled to work, the piston can be pulled to move downwards, the pressing block can be pulled to move downwards through the connecting rod, and the pressing block can abut against one end of the cover body outside the test groove, so that the cover body is fixed, and the cover body is prevented from loosening in the test process; and after the cover body is tested, the electro-hydraulic push rod can push the piston to move upwards, and one end, close to the piston, of the connecting rod can automatically eject the cover body out of the testing groove, so that the cover body is conveniently collected.
